DomainKeys Identified Mail, or DKIM, is a system for confirming the legitimacy of an email message using a digital signature. When DomainKeys Identified Mail is enabled for a particular domain name, a public cryptographic key is published to the global Domain Name System and a private one is stored on the mail server. When a new email message is sent, a signature is generated using the private key and when the email message is received, that signature is ‘scanned’ by the incoming POP3/IMAP email server using the public key. In this way, the receiver can easily tell if the message is legitimate or if the sender’s email address has been forged. A discrepancy will appear if the content of the email message has been edited in the meantime as well, so DKIM can also be used to ensure that the sent and the received emails are identical and that nothing has been attached or erased. This email authentication system will strengthen your email security, as you can confirm the authenticity of the important email messages that you get and your colleagues can do likewise with the messages that you send them. Depending on the given mail service provider’s adopted policies, an email message that fails the test may be deleted or may reach the recipient’s inbox with a warning.

DomainKeys Identified Mail in Cloud Hosting

If you host a domain in a cloud hosting account from us, all the necessary records for using the DomainKeys Identified Mail functionality will be set up by default. This will happen as soon as you add the domain in , on the condition that your domain also uses our NS records. A private key will be created on our email servers, while a public key will be added to the global DNS database automatically by using the TXT resource record. In this way, you won’t have to do anything manually and you will be able to enjoy all the benefits of this email authentication system – your emails will be sent to any audience without being rejected and nobody will be able to send out messages forging your e-mail addresses. The latter is very important in case the essence of your online presence suggests sending regular newsletters or offers via email to prospective and current clients.

DomainKeys Identified Mail in Semi-dedicated Servers

Our Linux semi-dedicated servers come with DomainKeys Identified Mail activated by default, so in case you opt for a semi-dedicated server plan and you add a domain name using our name servers through your Hepsia Control Panel, the records required for the email authentication system will be created automatically – a private encryption key on our email servers for the digital signature and a TXT resource record carrying the public key for the global Domain Name System. Since the DKIM protection is set up for a particular domain name, all e-mail addresses created under it will carry a signature, so you will not have to worry that the emails that you send may not reach their destination address or that somebody may forge any of your email addresses and attempt to spam/scam people. This may be rather important when you rely on e-communication in your business, as your partners and/or clients will be able to distinguish real messages from counterfeit ones.
